Definitions

  • the present invention relates to (1) a dental implant fixture mount-abutment (DIFMA), particularly to the DIFMA having (a) a fixture mount and (b) an abutment with internal (triangular, square, pentagonal or hexagonal) slots for a fixture mount driver to place a dental implant and the DIFMA simultaneously, (2) a ball impression screw (BIS) for making an impression immediately after implant surgery, and (3) a fixture mount driver having a latch type end/square type end, driver shank and body to torque a DIFMA by inserting into the driven channel of the DIFMA during placement of a dental implant and a DIFMA into alveolar bone.
  • DIFS ball impression screw
  • a fixture mount has been used by most of dental implant systems to deliver and place dental implants. After the dental implant placed, the FM is removed from the dental implant and is discarded. Three to six months after the dental implant placed, a conventional impression coping and copping screw are used for the purpose of making an impression to fabricate a stone cast for restoration which is not only a time consuming process but a waste of material due to discarding the FM.
  • the new design of the DIFMA is compelling because it can reduce cost, improve patient comfort and reduce clinical chair time/treatment time.
  • the present invention which is a new design can be used as a FM, impression copping, provisional abutment and/or permanent abutment. In other word, a device can be used for four (4) purposes.
  • This new design includes a DIFMA, a BIS and a fixture mount driver.
  • the DIFMA can be used as a FM, impression copping, temporary and/or permanent abutment.
  • the BIS can be placed on the top of the new designed DIFMA to secure the DIFMA immediately after the dental implant placed and impression can be made immediately after the dental implant surgery without waiting period to facilitate an immediate loading of restoration.
  • Patients can receive the benefits of chewing function and esthetics, immediately after the dental implant surgery, without a waiting period of three to six months.
  • WO 2009/054005 A2 describes a dental implant system comprising a dental implant, a multifunctional component and an abutment screw.
  • the multifunctional component has an upper portion for inserting the abutment screw, a middle portion and a lower portion having a hexagonal body for inserting the multifunctional component in the dental implant.
  • a main object of the present invention is to provide a DIFMA which is cost effective and is less expensive.
  • Another object of the present invention is to provide a DIFMA which reduces time of treatment (chair time).
  • Another object of the present invention is to provide a DIFMA which reduces waiting period of treatment (three to six months).
  • Another object of the present invention is to provide a DIFMA which can improve clinical convenience. (It is difficult to seat impression copping immediately after the dental implant surgery due to bleeding)
  • Another object of the present invention is to provide a DIFMA which can reduce office visits.
  • Another object of the present invention is to provide a DIFMA which facilitates/speeds the process of immediate loading for function and esthetic reasons.
  • Another object of the present invention is to provide a DIFMA which can increase patient comfort.
  • Another object of the present invention is to provide a BIS which provides additional surface for indentation/indexing can improves accuracy of impression.
